A regular nonagon has 9 sides and so its perimeter is 9*40 = 36 units of measurement
It is: 162/9 = 18cm
In a regular nonagon there are 9, if its irregular its dependant.
9 * 10.2 = 91.8 centimetres.
The regular nonagon will have 9 congruent isosceles triangles each with two equal sides of 13.1571198cm and two equal angles of 70 degrees with a base of 9cm opposite apex angle of 40 degrees. Area of triangle: 0.5*13.1571198^2 *sin(40)*9 = 500.7277596 square cm
It is the sum of the lengths of the nine sides of the nonagon.
90
You add together the lengths of the nine sides of the nonagon.
nonagon
If it is a regular nonagon then it has 9 equal sides, so all you needed to do was divide 31.23 by 9. (You would have got 3.47 cm)
A regular nonagon has 9 sides and so its perimeter is 9*40 = 36 units of measurement
The answer depends on what information you have. If you have the length of a side, then the perimeter is nine times that length.
Add the length of all nine sides up.
189 feet.
40
It is: 162/9 = 18cm
It is a nonagon. It need not be a regular nonagon.
